New Records of Arizona Wood-Rotting Fungi

Arizona has a rich flora of wood-rotting, higher Rasidiomycetes but the records for most groups are very incomplete. The Polyporaceae of the state are better known than other families. Records of many Arizona polypores have been given by Overholts (1953), Gilbertson and Lowe (1962), and Lowe and Gilbertson (1961). Larsen (1968) reports a number of tomentelloid fungi from Arizona. Burt (19141926), in his series of papers on the Thelephoraceae of North America lists relatively few Arizona collections. In this paper we record 178 species of woodrotting Hymenomycetes previously unreported from Arizona. These are all in the order Aphyllophorales. Voucher specimens are deposited in the University of Arizona herbarium and duplicates of most collections are also deposited in the National Fungus Collections, Beltsville, Md.
